A method for non-invasive measurement and multidimensional analyses of respiration and circulation was developed by using the respiratory mass spectrometer by combining a C2H2 mixture rebreathing method with a bag in box technique, various respiratory and circulatory factors are simultaneously obtained from continuous gas concentrations and respiratory flow rates. Respiratory and circulatory functions can be evaluated from relevant physiological aspects including ventilation, perfusion, gas exchange, ventilation perfusion ratio and the correlations between them. By applying microcomputer and special algorithms developed, an automatic system for real time measurement was constructed. Results show that the proposed system has the possibility of practical use in physiological research and clinical diagnoses.
